Thats why when answering queries on here i ask if people a token buyers/ power trainers. Its relevance more than opinion! I dont power train (though i do buy 80 tokens a season, purely as farming is more hassle than its worth) and find that training speed is pretty irrelevant as players, regardless of speed arent fast enough on normal training. For the big token buyer/pwer trainer then training speeds are very relevant as they want as much bang for their buck as they can get.
Think more people should state their preference (non token buyer/token buyer/power trainer/both) when asking questions so that the right people on here can give the right advice.
